Radiological Safety Training for Uranium Facilities

Module 104 Internal Dose Control

an evaluation of activities likely to generate or spread contamination,

use of containment devices to confine contamination as close to the source

as possible,

control and monitoring of airborne contamination as it is generated,

minimizing the size and number of contaminated areas by using effective

decontamination methods,

control of movement of equipment and personnel into and out of

contaminated areas,

use of personal protective equipment, and

effective contamination monitoring.

Evaluation of Work Activities

Work activities that involve the destruction of surfaces, such as grinding,

machining, filing, or cutting, can easily create and spread contamination.

Operations such as welding, burning, heating, etc. can alter the physical

and/or chemical state of uranium compounds that are on the surfaces of

equipment. Work activities such as these should be evaluated and steps

taken to minimize the spread of surface contamination, personnel

contamination, and airborne contamination. If possible, alternative

methods for completing the task should be considered.

Use of Containment Devices

Whenever activities that may generate loose contamination are planned,

consideration should be given to using containment devices to control the

contamination to an area as close to the source as possible. Such devices

include glovebags, gloveboxes, and tents.
